Patent CA-2272967-C (CA)
Inventor: ICHIRYU TAKU
IPC: F02C9/22
Filed: 1999-05-20
Granted: 2004-07-27
Abstract: A rotation mechanism for rotating a rotary ring which has the following features: the number of parts it requires will be reduced as much as possible; its configuration will be simple and economical to build; the operating drag of the ring will be low; any distortion resulting from the load or thermal expansion will be reliably absorbed; and the ring will be rotated reliably with a small operating force. This rotation mechanism rotates an annular rotation ring in which two follower links are connected to the periphery of the rotation ring in such a way that they are free to rotate. The follower links act to provide coupled forces to rotate the rotation ring. The central portion of a drive lever is rotatably mounted by an operating pin on the end of an operating lever which rotates on an operating shaft. Two drive links, each of which is connected at one end to a respective one of the follower links, are joined by pins to either end of the drive lever in such a way that they are free to rotate. When the operating lever is rotated, the force is transmitted via the drive lever and drive links to the follower links, which move simultaneously to form a couple. This as useful for rotating the adjustable fins of a gas turbine.
